Reclamation or restoration of sustainable native grasslands is constrained by the lack of seed of many difficult to harvest species. The lack of seed of many species stems from the lack of harvest equipment that can effectively dislodge, separate, convey, and off-load seed with challenging morphologies. The project will develop a pneumatic conveyance technology to integrate with the seed dislodgement and seed separation technology of the Arbuckle Native Seedster to produce harvester for difficult to harvest species of native grass that is much more productive that currently available harvesters.
